Genesis

Genesis World is an open-source simulation platform for robotics and embodied AI research, combining a unified multi-physics engine, a photo-realistic in-house renderer (Nyx), and a cross-platform compiler (Quadrants) behind a single Pythonic simulation interface. It's designed to scale from a single laptop up to datacenter-grade GPU clusters while staying readable and extensible for research code. The physics layer integrates multiple solvers — rigid body, FEM, MPM, particle-based (PBD/SPH), and more — sharing one scene and state, while the rendering layer offers three interchangeable paths (Nyx, the Luisa ray tracer, and a Pyrender rasterizer) that plug in as camera sensors. The Quadrants compiler lowers Python simulation code to CUDA, AMD ROCm, Apple Metal, Vulkan, x86, and ARM64, and includes built-in autodiff and GPU graph support. The project started as an academic effort (previously named simply "Genesis") in December 2024 and is now officially developed by Genesis AI.
